The Pentagon admitted on Wednesday that one of the airdrops of weapons intended for Kurds in the besieged Syrian town of Kobani almost certainly ended up in the hands of the Islamic State (Isis) fighters.
The Pentagon blamed the wind for possibly blowing the supplies off course and argued that one cache was not enough to make a significant difference to Isis.
Video footage released by Isis shows what appears to be one of its fighters in desert scrubland with a stack of boxes attached to a parachute. The boxes are opened to show an array of weapons, some rusty, some new. A canister is broken out to reveal a hand grenade. Other equipment appeared to be parts for rocket-propelled grenades.
